Positive Effects

The emergence of antibiotic-resistant bacteria in the intestinal microbiota of broiler chickens, and the possibility of antibiotic residues in meat and meat products are seen as a threat to animal and human health. The search for alternatives to conventional drugs, including natural compounds, is an interesting approach to prevent the adverse effects of antibiotics. Therefore, the aim of the present study was to evaluate whether the addition of tannin (as a quebracho extract) in the diet of broiler chickens could be used to replace in-feed antimicrobials and coccidiostatic drugs, to exert positive effects on animal health and performance. The use of tannin in the diet of broiler chicks as an additive (at 0.5% for 1–10-day-old birds; and 1.0% for 11–42-day-old broiler chickens) enhanced their bodyweight, weight gain and daily weight gain on Day 42 of life, compared with the untreated control group (P < 0.05). However, these findings were not observed when tannin was added at 0.5%. Moreover, broiler chickens fed with an extract containing tannins showed higher erythrocyte counts, as well as haemoglobin and haematocrit concentrations than did those in the control group, whereas counts of total leukocytes and lymphocytes were lower (P < 0.05). The use of a diet with tannins did not influence meat quality compared with a diet containing zinc bacitracin and salinomycin, which altered some parameters associated with meat colour. Moreover, the diet with tannins reduced (P < 0.05) the number of oocysts of Eimeria sp. (36-day-old broilers) and the total faecal bacterial counts (42-day-old broilers) compared with the control group. Finally, intestinal histopathology showed that the addition of tannins minimised the degree of lesions (Degree 1) compared with the control group (Degree 3). On the basis of these results, we concluded that the use of quebracho extract containing tannins can be a suitable approach to improve the performance of broiler chickens, replacing in-feed antibiotics and coccidiostatic drugs. The use of tannins did not change meat quality; however, it caused positive effects on the immune system, and exerted potent bactericidal and coccidiostatic properties, reinforcing its use as a replacement for conventional drugs.

This study was conducted to determine the effects of dietary supplementation of peppermint ( Mentha piperita L.) on the performance of broiler chicks. 500 Ross broiler chicks were divided into 5 treatment groups of 4 replications in a completely randomized design format. The diets were ISO-caloric and ISO-nitrogenous ones and contained 1.5, 3, 4.5, and 6 g/kg of peppermint powder. At start, growing, and end periods, the effects of peppermint powder on average daily weight gain, feed conversation ratio, and mortality rate were studied. The results of the present study showed that over a production period of 42 days peppermint had a significant effect on average daily weight gain and feed conversation ratio when compared with the control group ( P < .05). The level of 4.5 g/kg had the highest average daily weight gain (52.78 g), and control treatment with 46.98 g had the least average daily weight gain among different levels of peppermint. The level of 4.5 g/kg and 6 g/kg of peppermint had the least mortality compared to control treatment during training period ( P < .05). From this experiment, we can conclude that treatment with 4.5 g/kg peppermint powder has better performance and carcass characteristics in broilers.

Abstract The effect of graded levels of grains of selim on the performance, gut microbial population and carcass characteristics of finisher broilers was investigated. Two hundred and four (204) 28 days old broiler chicks (Marshal breed) were randomly allotted to four treatments with each treatment having three replicates of 17 chicks each in a completely randomized design. Finely blended grains of selim was administered through drinking water on treatments 2, 3 and 4 at concentrations of 0.5, 0.7 and 0.9 g per litre while chicks on treatment 1 (control) received 1.0 g per 1.5 litre of antibiotics (Gendox). Chicks were fed ad libitum with isonitrogenous and isocaloric diets containing 20% crude protein and 3000 Kcal/kg metabolisable energy for four weeks. Results showed no significant (P > 0.05) differences among treatments in the final body weight, total weight gain, daily weight gain, total feed intake, daily feed intake and feed:gain ratio. There were differences in the microbial population of the gastro-intestinal tract with colony count decreasing as the concentration of grains of selim increases. Carcass characteristics and organ weights were similar (P > 0.05) except for thigh and spleen weights, and large intestine lengths where differences (P < 0.05) exist. Mortality ranged from 8.47% - 13.47% across treatments. The results indicated that grains of selim have antimicrobial and anthelminthic properties, and promote growth in broiler chickens

Ad Libitum

Two hundred and twenty five day old straight run broiler chicks were utilized in completely randomized design to test the effect of restricting feed intake of four groups of chicks to 92.5% 85.0%, 77.5% and 70.0% of the unrestricted (control) group in the starter phase and following adlibitum feeding for all groups in the finisher phase. The treatments were simply designated as A, B, C, D and E. The starter phase in which the restriction was carried out lasted 28 days and the finisher phase 42 days. Parameters evaluated during the starter and finisher phases included; growth rate, feed conversion ration and mortality rate. Results show gain in weight among all groups while the group fed diet B and the control had comparable weight gain at the starter phase. The percentage weight difference between the control and each of the other dietary groups was: 4.4%, 8.4%, 8.6% and 10.4% for the treatments B, C, D and E respectively. Feed gain ration improved as the level of restriction became stricter. Following ad-libitum feeding of all grops at the finisher phase, the feed restricted groups at the starter phase voraciously increased their feed intake, thus, producing comparable performance values with the unrestricted (control) group in weight gain in the 8th week of the study. Although birds in all groups averaged more than 2000g final live weight in 10weeks, significant differences exist between groups that were fed diets C, D, and E that were restricted at the starter phase, an indication that complete compensatory growth was not obtainable. Feed gain ration improved for restricted groups. Mortality rate did not show any trend attributable to levels of feed restriction. This study shows that broiler chicks fed restricted levels of balanced diet at the starter phase but later fed ad-libitum at the finisher phase could attain a finished weight of about 2000g or more at a market age of 10 weeks (70 days) with an improvement in feed gain ration.

The aim of the study was to evaluate the growth rate and selected carcass and meat quality parameters in bulls fed a high-grain diet and to compare the results with those obtained in bulls fed a diet based on preserved roughage. The trial included 18 Czech-Pied bulls fed a diet with a high proportion of concentrated feed and 18 Czech-Pied bulls fed a diet based on maize silage, used as a control group. The trial was launched after the weaning of calves. During the fattening period, live weight and average daily weight gain were monitored. The bulls were slaughtered at the live weight of 550–600 kg, the mean age at slaughter was 473 days for the high-grain diet group and 474 days for the control group. The carcasses were classified to SEUROP quality grades, and carcass gain and dressing percentage were calculated. Samples of <I>m. longissimus pars thoracis</I> were taken from five bulls in each group to examine selected meat quality parameters. In the period from weaning to slaughter the high-grain diet bulls and the control bulls achieved the average daily weight gain of 1.29 kg and 1.21 kg, respectively. Differences between the groups were not significant. The high-grain diet group showed higher average carcass weight and higher carcass weight gain, differences between the groups were not significant, either. As to meat quality parameters under study, a significant difference was found only in meat lightness (L*), with the mean value in the high-grain diet group being significantly (<I>P</I> ≤ 0.01) lower than in the control group. The other meat quality parameters did not show any significant differences between the groups. In this study, the high-grain diet gave similar performance as the maize silage-based diet in fattening bulls. The high-grain diet group and control group showed comparable average daily weight gain and selected carcass and meat quality parameters.

Twenty Lithuanian Black-and-White calves (10 bulls, 10 heifers) were used to evaluate the effects of the supplemental probiotic product, Enterococcus faecium M74 (2.4 g/day/calve), added to fresh milk and skimmed milk in a 56 day-study. The probiotic was administered by dietary supplementation to first group of calves and their respective pens (probiotic group), whereas the second group (control group) received no probiotic supplementation. The results of this trial indicate positive effects of the probiotic product Enterococcus faecium M74. The actual percentage of calves with diarrhoea was reduced from 50 % to 20% among the calves fed the pre-and probiotic diet. Probiotic supplementation reduced the faecal count of clostridia and enterococci. The calves fed Enterococcus faecium M74 weighed more at 20, 40 and 62 days of age by 4.9%, by 9.7% (P &lt; 0.05) and by 9.4% (P &lt; 0.01), respectively, than the control calves. The calves fed Enterococcus faecium M74 had increased daily weight gains compared with the calves not fed a probiotic product. The average weight gain and the daily weight gain of the probiotic-supplemented calves were by 7.8 kg (P &lt; 0.01) and by 0.14 kg higher (P &lt; 0.01) compared with the control calves. The calves given the Enterococcus faecium M74 also had forage and total DM intakes that were numerically higher than those fed the control diet, without any additive. During the 56 days experimental period, the average feed conversion rate was improved by 12.9% in the probiotic-treated group.

An experiment was conducted to evaluate efficacy of Lacto acidophilus on the growth performance, carcass characteristics and nutrient digestibility of broiler chickens. Two hundred and twenty five (225), one day old chicks were purchased from local commercial hatchery and were randomly divided into 5 groups and each group had 3 replicates of 17 chicks in a completely randomized design. Five iso-caloric and iso-nitrogenous (ME 2998kcal/ kg and CP 23.21%) broiler starter and finisher (ME 2990 kcal/ kg and CP 20.33%) experimental diets containing 0, 150, 200 and 250g Lacto acidophilus® for T1-T4 respectively and T5 containing Oxytetracycline were formulated. Broiler starter and finisher diets were fed from 0-3 and 4-7 weeks, respectively. Data obtained were subjected to analysis of variance using Statistical Analysis System and significant differences between treatments means were separated using Duncan Multiple Range Test. There were significant (P<0.05) difference in final weight, weight gain, average daily weight gain (ADWG), total feed intake (TFI), average daily feed intake (ADFI), feed conversion ratio (FCR) and feed cost/kg gain across the treatment groups. It was observed that chickens fed dietary Oxytet (oxytetracycline) had the best results in terms of the final body weight, weight gain and ADWG but similar to those fed 150 and 200g Lacto acidophilus® addition levels. The percentage dry matter (DM), crude protein (CP), crude fibre (CF), ether extracts (EE) and ash retention increased with increase in Lacto acidophilus® inclusion with exception for 250gLacto acidophilus® inclusion (CP, CF, EE). However, it was observed that chickens fed dietary levels of Lacto acidophilus® had the best live weight, dressed weight and dressing percentage compared to the control group. It was concluded that chickens fe Lacto acidophilus® inclusion may as well compete favorably with antibiotics growth promoter fed chickens.     Une expérience a été menée pour évaluer l'efficacité de Lacto acidophilus sur la performance de croissance, les caractéristiques de la carcasse et la digestibilité nutritive des poulets de gril. Deux cent vingt-cinq (225), poussins d'un jour ont été achetés à l'écloserie commerciale locale et ont été répartis au hasard en 5 groupes et chaque groupe avait 3 répliques de 17 poussins dans une conception complètement randomisée. Cinq iso- caloriques et iso-azotés (le 'ME' 2998kcal/kg et le 'CP' 23.21%) démarreur et finisseur de poulet de gril (le 'ME' 2990 kcal/kg et le 'CP' 20.33%) des régimes expérimentaux contenant respectivement 0, 150, 200 et 250 g d'acidophilus lacto® pour le T1-T4 et le T5 contenant de l'Oxytetracycline ont été formulés. Les régimes d'entrée et de finisseur de poulet de gril ont été alimentés de 0-3 et 4-7 semaines, respectivement. Les données obtenues ont fait l'objet d'une analyse de la variance à l'aide du système d'analyse statistique et des différences significatives entre les moyens de traitement et ils ont été séparées à l'aide du test à distance multiple Duncan. Il y avait une différence significative (P<0,05) dans le poids final, le gain de poids, le gain de poids quotidien moyen (le 'ADWG'), la consommation totale d'aliments pour animaux (le 'TFI'), l'apport quotidien moyen en aliments pour animaux (ADFI), le ratio de conversion des aliments pour animaux (FCR) et le gain coût/kg des aliments pour animaux dans les groupes de traitement. On a observé que les poulets nourris oxytet alimentaire (oxytetracycline) ont eu les meilleurs résultats en termes de poids corporel final, gain de poids et de 'ADWG', mais similaire à ceux nourris 150 et 200g Lacto acidophilus® niveaux d'addition. Le pourcentage de matière sèche (le 'DM'), de protéines brutes (le 'CP'), de fibres brutes (le 'CF'), d'extraits d'éther (le 'EE') et de rétention de cendres a augmenté avec l'augmentation de lacto acidophilus® l'inclusion à l'exception de 250 glacto acidophilus® inclusion (CP, CF, EE). Cependant, il a été observé que les poulets nourris à des niveaux alimentaires de Lacto acidophilus® avaient le meilleur poids réel, le poids habillé et le pourcentage de vinaigrette par rapport au groupe témoin. Il a été conclu que les poulets feLacto acidophilus® inclusion peut aussi bien rivaliser favorablement avec les antibiotiques promoteur de croissance nourris poulets.

An experiment was conducted with one hundred and eighty (180) unsexed day old broiler chicks of Arbor acre strain to investigate the effect of feeding diets supplemented with water soaked sweet orange peel meal (SOP) on the performance and carcass characteristics of broiler chicken. The broiler chickens were randomly distributed into six (6) dietary treatments of 30 birds per treatment which were further distributed into three (3) replicates of 10 birds per replicate from day old, in a completely randomized design. Six dietary treatments were formulated such that, T1 which is control was maize based. In diets 2, 3, 4, 5 and 6, sweet orange peels replaced maize at various duration of water soaked, 0, 24, 48, 72 and 96 hours respectively and incorporated at 30% inclusion. Data were collected on feed intake and weekly weight gain. Six (6) birds were randomly selected per treatment starved over night, weighed and sacrificed by cervical dislocation for carcass analysis. Result reveals significant (p<0.05) difference in daily feed intake, there was no significant (p>0.05) difference on final weight and daily weight gain. The result of carcass characteristics showed no significant (p>0.05) difference in carcass cut and internal organs. It can be concluded that supplementing broiler diets with water soaked sweet orange peels had no detrimental effects on the performance and carcass characteristics.

Peel Extract

The study examined the effect of dietary antioxidant supplementation on the performance and meat quality of broiler chickens. Namely, 300 one-day-old Arbor Acres broiler chicks were fed a starter diet from 1 to 4 weeks and a finisher diet for the last 4 weeks. Birds were randomly assigned to treatments based on antioxidant supplementation in drinking water at 0.02% butylated hydroxyanisole (BHA), ordinary water (OW), 0.02% sweet orange peel extract (SOPE), 0.02% shaddock peel extract (SHPE) and 0.02% lemon peel extract (LMPE) per litre of water in a completely randomized design experiment. Feed intake and body weight gain were recorded on a weekly basis. Three birds were selected in each treatment and slaughtered for meat quality determination. BHA and LMPE treatments had the best weight gain and feed conversion efficiency at the significance level (p<0.05). There were significant differences (p<0.05) in the shear force (force peak and yield) in the dietary antioxidants fed to the birds. Sensory parameters (taste, aroma and overall acceptability) show significant differences (p<0.05) amongst the treatments. However, there were no significant differences (p>0.05) in appearance and texture perception amongst treatments. Finally, significant differences (p<0.05) in the lightness (L*) and redness (a*) of the meat samples were observed amongst the treatments. There were no significant differences (p>0.05) in the yellowness (b*) amongst the treatments. It can be concluded that broiler birds fed SOPE, SHPE and LMPE treatments performed better and that these treatments enhanced the meat quality of the birds when compared to BHA and OW treatments.

A 49 day feeding trial was conducted to determine the effect of biologically upgraded cocoa pod husk meal (BCPHM) on the growth performance, haemato-biochemical indices and antioxidant status of broiler chickens. Three experimental diets were formulated at both starter and finisher phases in which BCPHM was added as an active feed ingredient at 0, 10, 20% and designated as diets 1, 2 and 3 respectively. One hundred and fifty day old Marshal broiler chicks weighing 39±2.5g/bird were allotted to 3 dietary treatments (10birds/replicate, 50birds/treatment) in a completely randomized design. The Average daily weight gain (ADWG), total weight gain (TWG) and final body weight (FBW) of broiler chicks fed diets containing 10% BCPHM was significantly (p˂0.05) higher than that of control and diet containing 20% BCPHM at starter phase. At finisher phase, the values of ADWG, TWG  and FBW were at par with that of control. Feed Intake was seen to increase as BCPHM increased in the diet at finisher phase. Carcass traits, relative internal organ weight, haemato-biochemcal indices of broiler chickens were similar across dietary treatment. Superoxide dimutase (SOD) and Catalase (CAT) of birds fed control diet were significantly (p˂0.05) higher than those of birds fed BCPHM based diets. Ten percent dietary inclusion of BCPHM appears optimal in broiler diet since beyond this level growth performance declined.

The objective of this study was to evaluate the effects of feed supplementation with two prebiotic herbs—Origanum vulgare and Zingiber officinale—on growth performance of broiler chickens. The feed conversion ratio was determined weekly by dividing feed intake by body weight gain. A total of 400 one-day-old broiler chicks were divided into four treatment groups of four replicates of 25 chickens each using a complete design random. The four treatment groups were T0 (control), T1 (0.5% oregano), T2 (0.5% ginger), T3 (0.25% oregano + 0.25% ginger). The chicks were grown to 42 days of age. Weight gain, feed intake, conversion, carcass quality and mortality were determined weekly. Data analysis revealed that during the first 35 days of broiler chicken’s life, none of the dietary interventions had any effect on productive parameters (P > 0.05). However, during the last week of treatment, the oregano and ginger supplementation had a positive effect on weight gain and feed conversion (P < 0.05) than in the control group. In conclusion, the addition of oregano and ginger in the daily food ratio for broiler chickens during the last stage of the productive cycle improved the productive parameters, and carcass characteristics.
